14539	Cache-Control / Expires headers not applied to files in Multisite files location	spherical		"First reported in Multisite forum and detailed there:

[http://wordpress.org/support/topic/cache-control-headers-and-uploaded-files-not?replies=5]

These file type accesses should return 304s according to the rules in .htaccess but consistently return 200, showing an incorrect Cache-Control header specification, instead of no specification at all--which is still undesired.

This occurs in two 3.0.1 Multisite installs on all blogs, domain mapped or not, but does not occur on any other domains on the server or in any other file locations in the WP tree (themes, etc.).

Initially, it was image files that I had identified this on but a subsequent check of a CSS file in the files/ location returned the same header that is set for (.php|.pl|.cgi) files; same as the image files do.

Apache 2.2.15, PHP 5.2.13, FreeBSD 7.2-STABLE, MySQL 5.0.90
